Research institutes affiliated with Japanese national universities are organizationally 

equivalent to faculties and graduate schools. The main difference between research 

institutes and faculties and graduate schools is that the main mission of research institutes is 

to conduct advanced research. 

Tohoku University was founded in 1907 as Tohoku Imperial University: the third national 

university in Japan after those in Tokyo and Kyoto. The Research Institute of Electrical 

Communication (RIEC) was established in 1935 as a research institute affiliated with 

Tohoku Imperial University. At that time, in the Department of Electrical Engineering of 

Tohoku Imperial University, a growing tendency towards research marked science and 

technology for electrical communication. Great efforts made in these fields produced 

pioneering studies such as those of the Yagi-Uda antenna and divided anode-type 

magnetron, which were produced in the department in the late 1920s. Based on such 

prominent activities, RIEC was founded. In the seven decades since its foundation, RIEC 

continues to excel as the only national-university-affiliated research institute addressing 

information and communication technology, with various research fields encompassing 

hardware and software. In 1994, our research institute was promoted as a National Center 

for Co-operative research, addressing “theory and applications of intelligent information 

science and communication theory”. 

At present, it comprises 4 research divisions consisting of 23 research groups and 3 

research facilities with 12 groups. The four research divisions are the following. The 

Information Devices Division carries out research into materials and devices for 

communication technology. The Broadband Engineering Division specifically examines the 

development of new technologies for the transmission and storage of vast quantities of data. 

The Human Information Systems Division conducts research into intelligent information 

processing. The Systems and Software Division is developing advanced system software 

for the new information society. The three research facilities emphasize examinations 

organized into short-, medium-, and long-term projects. The Research Center for 21st 

Century Information Technology was established in 2002 to realize short-term (typically for 

five years) collaboration between the Institute and industrial partners. The Center seeks to 

develop information technology products using the advanced technologies and intellectual 

property developed at the Institute. For the medium term, the Laboratory for Nanoelectronics 

and Spintronics, housed in newly built facilities, is carrying out fundamental research into 

high-speed semiconductor devices and advanced nano-spin science. Smaller and faster 

electronic devices, non-volatile memories, and molecular and bio-information devices are 

some expected fruits of this research. Meanwhile, the Laboratory for Brainware Systems is 

working towards its long-term goal of the seamless fusion of real and virtual worlds at the 

human-computer interface. The Institute and its members aim to continue its tradition of 

world-class research and innovation into this century.

Fabrication of Plasmonic Nanosheets and their Bioapplication

The interdisciplinary field of research combining nanobiotechnology and information technology 

attracts our exceeding interests. These studies stand on the development of new materials created by 

self-assembly of functional molecules and nanomaterials, leading to new classes of biosensing devices. 

The plasmons, especially the combination of surface plasmons propagating along the metal-organic 

interface and local surface plasmons on metal nanoparticles is crucial to control and manipulate 

localized light in nano-scale for nano-sensing [1,2]. 

In this paper, we present our latest result concerning the coupling between propagating surface 

plasmons on flat gold surface and local plasmons on silver nanoparticles [2]. The silver nanoparticles 

(core diameter: 4nm) are deposited on the substrate as “nano-sheet” composed of two dimensional 

crystalline layer fabricated at air-water interface, in which the distance between the particle cores is 

controlled accurately by the thickness of the shell layers. We found the silver nano-sheet deposited on 

the glass exhibits a significant shift of plasmon absorption band in UV–vis–Near-IR spectra to the 

longer wavelength (c.a. 50nm), while the peak width was rather reduced (sharpened) in the sheet 

formation. By use of this ideal two dimensional giant crystals composed of silver nanoparticles, we 

examined several fundamental issues concerning the propagating and the local surface plasmons and 

their coupling effect on the optical responses. This flexible, transferable nanosheet which can trap and 

transport bulk light efficiently is the promising building block for various types of plasmonic biodevices.

The aim of this study is to use a microsensor (SGFET) that detects charges with high 

sensitivity and is developed at IETR, to achieve selective biosensors. This sensor is adapted for the 

detection of specific proteins, here transferrin, for diagnosis and therapeutic applications in 

human health. 

This project is financed by the Agence Nationale de la Recherche (ANR DEPIST) and 

associates complementary skills with biologists, chemists, electronics specialists and clinicians. 

The sensing structure is a field effect transistor with a 

suspended gate. 1 Charge detection is performed by electric 

measurements (shift of the transistor characteristics) induced by the 

immobilized biological species. This particular technology allows 

reaching high level of sensitivity 2 . Moreover, its small size should 

lead to the fabrication of a matrix sensor for the simultaneous 

detection of different proteins and so to the achievement of a new 

type of lab-on-chip. The previously elaborated technology was improved to adapt the sensor to 

biological medium (complex medium with salts and proteins). 

The quantification of proteins is obtained by anchoring them in a selective manner. 

The selectivity of the sensor can be obtained by a good choice of sensitive layers deposited on 

the active surface (functionnalization), and by the use of antibodies allowing the specific 

binding with the target proteins. Preliminary measurements were performed using a 

glutaraldehyde linker. The results show the feasibility, but the reliability of the biosensor 

cannot be obtained without an efficient and reproducible functionnalization of the surface. A 

new functionalization 3 , developed by the chemistry team, was used. A stepwise 

functionnalization of silicon nitride surfaces was achieved. The first step involves a 

silanization reaction leading to the formation of a silane film with a thickness estimated by 

XPS of one or two molecular layers. A monoprotected homobifunctionnalized linker is then 

grafted to avoid the formation of bridge structures on the surface. Deprotection of the ester 

groups of the immobilized linker and subsequent reaction with N-hydroxysuccinimid lead to 

N-hydroxysuccinimid activated surfaces able to react with biological species. The 

compatibility of the functionnalization procedure with the microsensor technology was 

checked. The device, the first results on functionnalization with electrical control, the 

selectivity after unspecific binding saturation and the range of transferrin detection will be 

described here.

Research activities: 

The continuously increasing amount of data to be stored and manipulated 

is strong impetus in the search for molecular electronic devices that are 

fabricated from various molecules with unusual electrical and optical 

properties. The use of supramolecules such as C60, organic metals and 

semiconductors, and biomolecules such as DNA will open entirely new 

horizons in the field of molecular device technology. The need to manipulate 

large amounts of genetic data requires the development of new types of 

bio-information devices, which may be constructed by combining molecular 

device technology with biotechnology. 

In accordance with these requirements, we are now searching for new 

types of molecular materials to be used in molecular devices, while 

simultaneously trying to produce new types of molecular chemistry with the 

enormous existing infrastructure in silicon technology. Our goal is the 

realization of molecule-sized electronic devices that enable signal generation, 

processing, transfer, amplification and more on the molecular scale.

1. Analysis of biological functions at semiconductor surfaces Development 

of bio-sensing systems

Detecting biomolecular interactions is often the most critical step not only for biosensor and 

biochip applications but also for understanding the underlying mechanisms of their actions. The 

most common approach for detecting their binding relies on labeling of proteins with 

fluorescence, radioisotopes or enzymes to achieve highly sensitive detection. However, labeling 

may affect their biological activities, especially for the small proteins or peptides. On the other 

hand, non-label detection of the binding events based on the structural and conformational 

changes is another useful approach, because this approach does not perturb the biological 

activities of the target molecules. Furthermore, such structural change is specific for the 

interactions, leading to more precise discrimination between specific and non-specific 

interactions, which is sometimes very difficult for the labeling approaches. 

Fourier-transform (FT) infrared spectroscopy (IRAS) is a powerful tool for non-label 

detection of structural changes induced by biomolecular interactions. IRAS has several 

advantages such as rapidity, easiness and applicability to various environments including crystals, 

aqueous solutions and optically turbid conditions like cell culture media. In addition, IRAS has 

potential to provide information on multiple target molecules, which is particularly useful when 

we are monitoring dynamic and complex biomolecular systems. IRAS in the multiple internal 

reflection (MIR) geometry provides an ideal optical configuration to combine highly sensitive 

detection and aqueoussolution phase measurements. By using MIR-IRAS we have recently 

succeeded in detecting antigen-antibody interaction in aqueous solution without using high 

sample concentrations. 

We focuses on our MIR-IRAS approaches for label-free detection and characterization of 

biomolecular interactions, such as DNA hybridization, DNA hydration, protein-protein 

interaction, cell growth and cell death. These biomolecular interactions were monitored both in 

D2O and H2O media. We demonstrate the utility of MIR-IRAS as an in situ monitoring both for 

analysis of biomolecular interactions and for the sensitive detection of target biomolecules and 

their interactions.

A chemical synthesis and modification of DNA/RNA is the fundamental technology that has led the 

molecular biology revolution. Hence, a chemistry of DNA and RNA not only in vitro but also in vivo 

expects to open new generational stage of bioorganic chemistry and molecular biology, then the nucleic 

acids chemistry has received much attention in post-genome project era. Thus, focusing our research 

interest mostly on the recognition and complexation behavior control of biopolymers, such as DNA/RNA, 

proteins by external factors, toward the active control of cellular functions. 

Another topics are reaction control based on molecular recognition phenomena in both ground and 

electronically excited states; we are pursuing mechanistic and synthetic studies on asymmetric 

photochemistry with supramolecular biopolymers as chiral reaction fields.

Nature is an unlimited source of inspiration for the development of materials presenting 

original mechanical or optical properties . The current structural knowledge of some of these 

biological assemblies is promising as an inspiration source to try to mimics their 

supramolecular organizations. The development of simplified system presenting properties 

close to biological assemblies is of great interest. To this end, there is still a long way in order 

to understand not only the structures, but also their formation mechanisms. 

Lanreotide molecules self-assemble in water into highly monodisperse 

supramolecular nanotubes, the diameter and wall thickness of which are 244Å and 18Å 

respectively. [1] Following biomineralization principles, we show that the self-assembled 

nanotubes can be used as a template to produce micron-long, bilayered silica nanotubes 

having a monodisperse diameter of 29 nm. The nanotubes organize spontaneously into 

centimeter-size, highly ordered bundles. Furthermore, the formation mechanism was 

elucidated using a range of techniques, including X ray diffraction, optical and electron 

microscopy [2].

Inelastic tunneling spectroscopy of C8 alkanethiol self assembled monolayer 

using scanning tunneling microscopy at 4.3 K 

IMRAM, Tohoku Univ., CREST-JST 

Tadahiro Komeda (komeda@tagen.tohoku.ac.jp) 

The development of the minitualization technology enables to employ a single molecule for a device application. 

For example, intensive studies have been executed for the understanding of electron transport through a single 

molecule that bridges two metal electrodes. The results have revealed intriguing electric phenomena, but the 

necessity of the characterization of molecules between electrodes has also been realized and it is mandatory to 

visualize and characterize an individual molecule. However, the use of TEM microscope is not favorable due to 

the damage to molecules. Scanning tunneling microscope (STM) has a big advantage for this purpose due to the 

low energy of injected electrons and small damage for molecules. STM can also be used to characterize and 

manipulate a single molecule. Inelastic tunneling spectroscopy (IETS) is one of the characterization techniques, 

which reveals the vibration features of molecules. Here, we report STM-IETS mesurement of C8 alkanethiole 

self assembled monolayer (SAM) at 4K. C8 SAM was prepared by immersing Au(111)/mica sample 

into hexane solution of C8 (1mM) for 6 min, and rinsed by ethanol just before inserted into a 

vacuum chamber for STM observation. The surface shows √3x√3 R30o ordered structure as shown in 

Fig.1 which is consistent with previous works. Figure 2 shows a comparison of I, dI/dV and d2I/dV2 obtained simultaneously at 4.3 K; the d2I/dV2 shows an excelent agreement with the previous work of 

Kushmerick et al using cross-wire method. Figure 3 corresponds to a high resolution SWTM-IETS spectrum 

with smaller modulation voltage for the bias voltage (Vrms=3.6 mV for modulation) of the C8 SAM. Feature of 

CH2 rocking (mark D, 88meV), CH3 rocking (E, 108meV) C-C streching (F, 130meV), and CH3 deformation (K, 

171meV) are highlighted and show a good consistency with the ones detected with electron energy loss 

spectroscopy. This is the first demonstration that STM-IETS can reveal practically all the vibrational modes 

detected with using EELS technique.[1]

Structuring of Liquids at the Solid-Liquid Interface 

Kazue Kurihara 


Katahira, Aoba-ku, Sendai 980-8577, Japan, e-mail: kurihara@tagen.tohoku.ac.jp 

Liquid molecules, confined between nanometer scale space and at the solid-liquid interfaces, 

often exhibit quite different properties from those in the bulk. We have investigated the 

structuring of liquids at the solid-liquid interfaces employing new approaches based on surface 

forces measurement. Surface forces measurement, which directly measures molecular and 

surface interactions as a function of the surface separation, is a unique tool for surface 

characterization, enabling us to “monitor surface properties changing from the surface to the bulk 

(depth profile)”. 1 This paper describes our recent researches including: 

Hydrogen bonded molecular macroclusters on silica surface. 2-4 Liquid adsorption from 

binary liquids was investigated. Novel molecular architectures, macroclusters of alcohol, 

carboxylic acid or amide, have been found on silica (glass and oxidized silicon) surfaces in 

non-polar solvents such as cyclohexane. Surface forces measurements revealed the long ranged 

attraction (e.g. extending to 30 ~ 40 nm for mono-alcohol), which associated with the macrocluster 

formation. FTIR-ATR spectroscopy has demonstrated that macroclusters are formed through 

hydrogen bonding between the surface silanol groups and adsorbed molecules and between 

adsorbed molecules. This phenomenon is used for preparing polymer nano-films by in-situ 

polymerization of precursor macroclusters on silica. 

Resonance shear measurement of confined 

liquids. 5-9 Resonance shear method has been developed 

in order to examine the ordering behavior of liquid and 

liquid crystal molecules confined between two solid 

surfaces at the nanometer level. The frequency and the 

amplitude of the resonance peak are highly sensitive to the 

long-range order of the confined molecules, affording the 

information about the viscosity, and lubrication and Figure. Resonance shear 

friction properties of confined liquids. The mechanism of 

measurement. 

nano-colloid viscosifiers has been also investigated.

The manipulation of fluids in nanochannels has become a crucial issue for many foreseen 

applications in advanced nanomaterials and biotechnology. 1 

Fundamental questions arise from the unexpected behaviors of fluids confined in capillaries 

of nanometric dimension, which rule out the validity of some approaches derived from the 

physics of liquids at the macro or microscopic scale. 

Intensive experimental studies of molecular liquids have shown that confinement on a 

nanometric scale considerably modifies the structure, phase behavior and molecular 

dynamics. Recently, much effort has focused on the unusual dynamic properties of lowmolecular 

weight liquids and glassforming systems in mesoporous solids. It reveals a 

complex entanglement of low dimensionality, finite size and surface effects. 2 

In this field, a current challenge is to extend the knowledge of nanoconfined liquids to more 

complex fluids such as soft matter or solutions of biological interest. The aim of the present 

contribution is indeed to present some original features that are observed, when the confined 

system is tuned from pure globular liquids to anisotropic mesogenic molecules or multicomponent 

glassforming bioprotectant solutions. 3

The design of molecular materials which exhibit specific electronic properties is 

becoming one the main issue of contemporary research. As a result, molecular magnetism has 

attracted much attention in the last two decades because molecular-based magnetic materials 

may possess properties that cannot be found in classical materials made from solid state 

chemistry. For example, molecules can act as a true molecular magnet at low temperature; the 

so-called Single Molecule Magnets (SMMs). It has been recently discovered in molecular 

edifices that one-dimensional magnetic arrays can also act as a magnet, with out, of course, 

three-dimensional magnetic ordering. 

The carboxylate chemistry has been deeply involved in the field of molecular magnetism 

mostly to generate polynuclear homometallic complexes. Various methods have been 

developed to synthesize polynuclear complexes. However, till now the carboxylate ligands 

were already incorporated in coordination core or were involved in the reaction solely as 

nucleophile and did not participate in any redox process during the reaction. Furthermore, metal 

carboxylate salts are not soluble in noncoordinating solvents, and this leads to the limitation of 

their use as starting materials. The method we propose is based on the in-situ redox generation 

of the benzoate ligand from metal nitrates. This efficient procedure leads to homo- and 

hetero-metallic discrete complexes as well as 1D coordination polymers, charged or neutral 

depending on experimental conditions. 

In this presentation we will give an overview of the library of materials we obtained. 

Specific attention will be given on the use of this method to synthesize polynuclear complexes 

with redox-active ligands such as tetrathiafulvalene derivatives. 

Olivier Cador is born in 1972 in Rennes (France). He defended his 

PhD thesis, supervised by Prof. Olivier Kahn, in 1998 in 

Bordeaux. He is assistant professor at University of Rennes 1 

since 2003. His field of research includes magneto-structural 

correlations in molecular-based edifices and the understanding of 

electrical properties in molecular conductors.

A ‘Metal Atom Cluster’ according to Cotton’s definition is a ‘finite group of metal atoms that 

are held together (...) by bonds directly between the metal atoms (...)’. Octahedral metal atom clusters 

are commonly associated with halogen (X) or chalcogen (Q) ligands to form M6(Q,X) i 8X a 6 units (i = 

inner, a = apical; Fig.1). They are obtained by solid state reactions (M = Mo, Re) at high temperature. 

The unit is the smallest entity that enables the description of physical properties, crystal and electronic 

structures of solid state compounds. Their dissolution affords discrete nanometric M6(Q,X) i 8X a 6 units 

that exhibit interesting optical, electronic and magnetic intrinsic properties usable in the design of 

hybrid supramolecular assemblies and materials by solution chemistry. We present here a review of 

our recent results on nanomaterials based on metal atom clusters. 

Figure 1 

Inorganic Mo6X i 8X a 6 units were used in the synthesis of phosphor silica nanoparticules (Fig.2) 

by water in oil microemulsion technique and in the design of tunable emitting ZnO colloids. On the 

other hand, after apical ligand exchange (in solution or in organic melt), functional M6(Q,X) i 8L a 6 

hybrid building blocks were used in the design of novel nanomaterials. Indeed, owing to the covalent 

and ionic natures of the M-(Q,X) i and M-X a bonds respectively, the M6(Q,X) i 8 core remains rigid 

whilst the apical ligands can be replaced by functional organic ones (L). The synthesis, structure and 

properties of nanomaterials based on functionalized cluster units will be presented: the fac- 

Re6Q i 7Br i Br a 3L a 3.xH2O Metal Organic Framework (L = pyrazine, Fig. 3), polymers based on trans- 

Re6Q i 8(TBP) a 4L a 2 units (L = methyl-metacrylate) and modified semiconducting surfaces on which 

clusters are anchored through an organic linker (Fig.4). 

Figure 2 Figure 3 Figure 4 

To conclude, M6L i 8L a 6 constitute relevant building blocks with specific physico-structural properties 

for the elaboration and structuration of hybrid materials for nanotechnologies.

Characterization of Microscopic Chemical State and Composition of 

Complex Metal Oxides 

Shigeru Suzuki and Kozo Shinoda 


The partial pressure of oxygen in atmosphere is known to affect the structure and 

chemical state of metal oxides at room temperature as well as at high temperatures. For 

instance, Green Rust (GR), whose structure is characterized by layered structure of 

Fe(II) and Fe(III), is instable under ambient atmosphere and oxidized to other iron 

oxides, like goethite. The structure and chemical state of these metal oxides have been 

analyzed by using X-ray absorption spectroscopy, X-ray diffraction method and so on. 

Several experimental results on the chemical state and structure of complex oxides such 

as cathode materials for solid state oxides for fuel cell will be shown in this 

presentation. The chemical state and composition are considered to play an important 

role in these cathode oxide materials, as their properties are known to depend on an 

oxygen potential or partial pressure of oxygen. Therefore, constituent elements in the 

cathode oxide materials may exhibit different chemical states or compositions, 

depending on the oxygen partial pressure. Moreover, the cathode oxide materials are 

likely to reveal different chemical states and compositions from the surface to the bulk. 

Depth-resolved X-ray absorption spectroscopy (XAS) and X-ray photoelectron 

spectroscopy (XPS) have been applied for analyzing the gradient of the chemical state 

and composition non-destructively. In depth-resolved X-ray absorption near edge 

structure measurements, XANES spectra were obtained by measuring fluorescence 

X-ray at different take-off angles while synchrotron radiation with different energies 

were irradiated to the sample surface. The XANES spectra by depth-resolved X-ray 

absorption near edge structure measurements sometimes demonstrated changes of the 

chemical state of transition metals in an oxide layer, although precise analysis of the 

spectra is necessary. Angle-resolved XPS measurements were also used for analyzing 

changes in the chemical state and composition in the oxide layers. In the presentation, 

the inhomogeneous state of elements in the oxides is discussed on the basis of these 

results.

Among functional oxides, ferroelectric thin films are attractive materials for many applications, such as 

devices like FeRAM as well as in electrically tunable high frequency devices, in relation with the large 

variety of related properties. Their practical use currently requires a capacitance-like geometry, meaning 

either the presence of a bottom electrode or a coplanar-like configuration. Constraints due to anisotropy 

of the ferroelectric material and future needs for miniaturization motivate efforts to master the epitaxial 

growth of ferroelectric films and consequently of the eventual bottom electrode. Moreover integration in 

microwaves devices implies the control of high quality thin films on specific substrates suitable for high 

frequency range. 

We investigated the perovskite-like oxide KTaxNb1-xO3 (KTN). Indeed, KTN is a promising candidate 

for microwave tunable devices due to its dielectric properties and tunable Curie temperature Tc which 

can be monitored by the composition x. Previous to any application, the first step is the control of thin 

films composition and structure. 

High quality KTN films can be achieved on various substrates provided the deposition conditions are 

accurately controlled. We optimized the composition of KTN thin films by Pulsed Laser Deposition 

(PLD) as well as by Chemical Solution Deposition (CSD) according to the potassium volatility but also 

in regard with the competition between the perovskite phase and the undesired pyrochlore phase. We 

evidenced the main role of the substrate and the influence of seed layers. 

Thin films were grown by PLD on single-crystal insulating substrates or on specific bottom electrodes. 

Films on bare sapphire are textured while those on MgO and LaAlO3 reveal an epitaxial growth. Phase 

purity, orientation and crystalline quality of perovskite (100)-oriented KTN on sapphire are greatly 

improved by the use of the KNbO3 seed layer [1]. 

CSD experiments were also performed with success: single phase perovskite KTN films were grown, 

with structural characteristics strongly depending on the substrates [2]. Epitaxial-like films were obtained 

on LaAlO3 substrates, and also on sapphire provided the use of a KNbO3 seed layer. These results open a 

simple way for deposition on large area substrates. 

The value of the refractive index close to the one of the bulk confirms the high quality of the films, 

whereas its evolution with the composition (x) illustrates the actual control of the films synthesis [3]. 

The evolution of coplanar microwaves devices versus an applied bias voltage evidences the high 

potentiality of KTN thin films to achieve tunable microwaves devices [4,5]. The influence of the KTN 

composition on tunability and more generally on the physical properties will be discussed.

Magnetic Domain Wall Dynamics in (Ga,Mn)As

A ferromagnetic semiconductor (Ga,Mn)As exhibits a well defined magnetic domain structure and its domain wall 

(DW) motion can be displaced by the application of electrical current with a few orders smaller density than its metallic 

counterparts [1]. In this work, we have measured the velocity of current-induced DW motion. 

The 30-nm thick (Ga,Mn)As with x = 0.045 was grown by molecular beam epitaxy on a semi-insulating GaAs (001) 

substrate. In order to make the magnetic easy axis perpendicular to the sample surface, an (In,Al)As buffer was inserted 

between the (Ga,Mn)As layer and the substrate [1]. After the formation of a 5-µm wide electrical channel along [-110] by 

photolithography and wet etching, a part of the channel surface was etched away by 10 nm; a 60-µm long etched region (I), 

where the DW was swept, and a 20-µm long nonetched region (II). This structure allows us to initialize the DW position at 

the boundary of the two regions by using an appropriate application sequence of an external magnetic field H [1]. After 

preparing the DW at the step boundary, the current pulses were applied at H = 0, which induced the DW motion to the 

opposite direction to the current. We measured the current-induced DW velocity veff as a function of the device temperature T 

and current density j. The effective velocity veff of the DW was determined from the observation of the domain structure 

using magnetooptical Kerr effect (MOKE) microscope. 

The j dependence of veff at a fixed T showed that there are two distinct regimes separated by a threshold current density 

jC, which is a few 10 5 A/cm 2 . Above jC, veff increases linearly with j, while below jC, veff is low and its functional form seems 

to be more complex. The linear dependence of veff above jC is found to be in quantitative agreement with what is expected 

from the spin-transfer mechanism [2]. The j dependence of veff below jC is found to obey an empirical scaling law, showing 

the existence of current-induced DW creep [3]. The comparison between current-induced and field-induced DW creep 

reveals that both follow a similar scaling law but with the different scaling exponents, indicating the j drive and the H drive 

act on DW in fundamentally different ways. A creep model based on spin transfer torque explains the obtained critical 

exponents well. 

The work has been done with M. Yamanouchi, D. Chiba, T. Dietl, J. Ieda, S. E. Barnes, and S. Maekawa. The work was partly supported 

by the Grant-in-Aids from MEXT/JSPS, the GCOE program at Tohoku University, and the Research and Development for 

Next-Generation Information Technology from MEXT.

BEEM investigation of some spintronics heterostructures

Ballistic electron emission microscopy (BEEM) is a unique experimental tool which allows 

characterization of the electronic properties of buried interfaces with nanometric lateral resolution [1]. 

In this talk, we will discuss experimental BEEM investigations on some spintronics heterostructures. 

We will first focus on the electronic properties of epitaxial MgO tunnel barriers grown by 

molecular beam epitaxy. Such tunnel barriers have been succesfully used in 

Fe/MgO/GaAs(001) spin-injector and demonstrated high spin-injection efficiency at roomtemperature 

[2]. Epitaxial MgO tunnel barriers are also now commonly integrated in magnetic 

tunnel junctions with record magnetoresistance values [3]. We have investigated by BEEM 

Au/MgO/GaAs(001) MOS structures. In these experiments, the STM tip is used to inject 

locally a hot-electron current IT into the Au gate of the MOS structure, with an energy defined 

by the applied STM tunnel voltage Ugap. A small part of the injected electron beam travel 

ballistically through the metal layer and reaches the Au/MgO interface. If their energy is high 

enough to overcome the tunnel barrier height, these ballistic electrons can enter into the 

conduction band of the oxide layer, and a BEEM collector current IC can finally be detected in 

the GaAs substrate. For this system, large scale BEEM images demonstrate the absence of 

conduction hotspots in the MgO tunnel barrier. The tunnel barrier height of Au on the 

MgO/GaAs heterostructure is determined to be 3.90eV, in good agreement with spatiallyaveraged 

X-ray photoelectron spectroscopy measurements. Locally, two well-defined 

conduction channels are observed for electrons energies of 2.5eV and 3.8eV, i.e. below the 

conduction band minimum of the oxide layer. These conduction channels are attributed to a 

band of defects states in the band-gap of the tunnel barrier related to oxygen vacancies in the 

MgO layer. These defects states are responsible for the low barrier height measured on 

magnetic tunnel junctions with epitaxial MgO(001) tunnel barriers. 

Finally, we will present preliminary BEEM results obtained under magnetic field on the 

epitaxial Fe(1nm)/Au(3nm)/Fe(1nm)/GaAs(001) spin-valve structure. For this sample, the hot 

electron current is additionally modulated by the local giant magnetoresistance (GMR) effect. 

Thus, BEEM allows the investigation of hot-electron spin-dependant transport for electronenergy 

between 0 and 10eV and can also be used for magnetic imaging with nanometric 

lateral resolution.

In order to understand the properties of advanced materials, it is fundamentally important 

to analyze their microstructures accurately. In addition to the microstructures, clarification of 

electric and magnetic fields both inside and outside the advanced materials is quite useful. For 

visualizing the electric and magnetic fields, we have carried out electron holography on 

various advanced materials. In the systematic studies with electron holography, we have 

utilized a newly designed double-probe piezodriving holder. By utilizing this holder, the 

electric field can be partly shielded and thus the reference wave without disturbance due to 

the electric field can be obtained. Eventually, quantitative analysis of the electric field is now 

possible. 

For the analysis of magnetization of magnetic materials, in situ observation of 

magnetization with the strong magnetic field applied is efficient. In order to introduce the 

strong magnetic field, a small magnetic needle made of a permanent magnet is driven by 

utilizing the piezodriving holder. Recently we also installed an alternating current (AC) 

magnetic system for investigating the dynamic motion of domain walls in electrical steel 

sheets. 1) As shown in Fig.1, the precipitates and the strain field around them are clearly 

observed by controlling the diffraction condition. Under this condition, the interaction 

between the magnetic domain walls and precipitates/ strain field can be observed. 

It is noted that electron holography and Lorentz microscopy combined with a double-probe 

piezodriving holder and an AC magnetic system is promising for extensively carrying out 

electric and magnetic field analysis on advanced materials. 

Fig.1 Lorentz micrographs of non-oriented electrical steel sheet under the two-beam 

condition of the bright field image. When an AC magnetic field (sine wave 1.0 Hz, 2.4 

kA/m) is applied, it is observed that the domain walls are trapped at not only the 

precipitates (a), but also by their strain fields (b).

The facile and reversible M(II)/M(III) redox process exhibited by several Fe(II) and Ru(II) σarylacetylides 

fragments of formula "L4XM(C≡C-Ar)-" might be conveniently be used to switch the 

second and third-order NLO-activity of various mono- and polynuclear assemblies containing these 

fragments, like 1-3 (Fig. 1), between several redox states. 1 We will first show that redox switching 

between two or three redox states can indeed be accomplished in solution at the molecular level. 2 

Finally, recent attempts to heterogeneize mono- and binuclear compounds related to 1 and 3 in order 

to obtain new NLO-active or redox-switcheable hybrid materials will be reported. 3

Growth of InAs/InP Nanostructures 

for Optical Telecomunication Devices. 

Olivier Dehaese 

FOTON (UMR CNRS 6082) – INSA de Rennes 

Self-assembled semiconductor nanostructures, such as Quantum Dots (QD) or Quantum 

Dashes (QDH) grown by Molecular Beam Epitaxy (MBE) using the 

Stranski-Krastanow growth mode have been widely studied in the recent years. Their 

improved optical properties as compared to Quantum Wells (QW) have lead to highly 

efficient optoelectronic devices. To reach the 1.55 µm range required for optical 

telecommunication devices, growth on InP substrates is required. This talk will present 

the main results on the growth and characterization of InAs nanostructures on InP 

substrates obtained in the lab. 

Due to a lower lattice mismatch between InAs and InP (3%) in comparison with the 

InAs/GaAs system (7%), the Stranski-Krastanow growth mode leads to InAs 

nanostructures with different morphologies (dots, elongated dashes or isotropic islands) 

depending on the InP substrate orientation and on the growth conditions (mainly the As 

flux). QD are observed on InP(311)B substrate with a density reaching 1x10 11 cm -2 

when the As flux is decreased to 0.3 sccm. More than 6 layers of these QD could be 

stacked without degrading their optical properties. Wavelength emission of such QD 

could be accurately controlled from 1.4 µm to 1.6 µm. These QDs have been 

demonstrated to be very efficient as active region of broad area lasers with very low 

threshold current density and also for ridge waveguide Fabry-Perot lasers. 

On InP(100), the nanostructure morphology is highly dependent on the As flux. For low 

As flow rates (

InP-Based High Electron Mobility Transistors for Millimeter-Wave 

Applications and Plasmon-Resonant Devices

From its invention in 1980, high electron mobility transistors (HEMTs) have been 

developed primarily for microwave and millimeter-wave integrated circuits. In particular, 

InAlAs/InGaAs HEMTs on InP substrates (InP HEMTs) are promising devices to achieve ultra-high- 

frequency response because of their large carrier mobility and large carrier concentration realized by 

the conduction band offset at InAlAs/InGaAs heterojunction. 

We are developing the fabrication technology for InP HEMTs with a gate length of sub- 

100 nm using electron beam lithography. Figures 1 and 2 show the device characteristics of our 

HEMTs with a gate length of 110 nm, exhibiting a maximum current of 340 mA/mm, a maximum 

transconductance of 430 mS/mm, and a current gain cutoff frequency of 163 GHz. These 

performance will be improved by optimizing the device design and process condition. Based on 

HEMT structures, we also carried out a study of novel functional devices in terahertz frequency 

range using plasmon-resonant phenomena. 

The device fabrication is carried out at the Laboratory for Nanoelectronics and Spintronics 

of RIEC in Tohoku University.

Various recent achievements on millimeter wave antennas and metamaterials will be 

presented. These studies include micromachined antennas and microsystems for millimeter 

waves applications (planar micromachined patch antennas and arrays [1], MEMS-based 

reconfigurable antennas for polarization and beam diversity applications [2,3]), antennas for 

broadband communications and imaging systems from Ka- to V-band (integrated lens 

antennas [4], reconfigurable lens antennas, reflectarrays [5], electromagnetic band gap 

resonator antennas [6,7]), and periodic structures and metamaterials (e.g. homogenization of 

metamaterials [8] and quasi-TEM resonant cavities). The study of biological effects of lowpower 

millimeter waves will be also discussed [9].

Ronan SAULEAU graduated in 1995 from the “Institut National des 

Sciences Appliquées” (INSA), Rennes, France, in Electrical Engineering 

and Radiocommunications and simultaneously obtained his Master by 

Research in “Radiocommunications”. He joined the “Ecole Normale 

Supérieure de Cachan” (ENS) in 1995 and received the “Agrégation” in 

1996. He received the Doctoral degree in Signal Processing and 

Telecommunications from the University of Rennes 1 in Dec. 1999. He was 

an Assistant Professor from 2000 to 2005 at the University of Rennes 1 

where he is now an Associate Professor (he received the “Habilitation à 

Diriger des Recherches” in 2005). He was promoted as a member of the 

“Institut Universitaire de France” (IUF) in Sept. 2007. 

His main research areas include the modelling and design of 2-D and 3-D antennas at 

millimeter waves (micromachined antennas, planar antennas, integrated lens antennas, 

reconfigurable MEMS-based antennas), and periodic structures (Electromagnetic Band Gap 

materials, metamaterials, Fabry-Perot antennas, passive and reconfigurable periodic 

structures using active components and smart materials). His research works also include 

numerical modelling (time domain formulation, electromagnetic synthesis and optimisation 

based on high-frequency and full-wave techniques) and participation in the development of 

specific antenna technologies (micromachining techniques, thin film technologies and 

MEMS, reconfigurable materials, ultra-soft polymers). Dr Sauleau is involved in multidisciplinary 

research studies at IETR, namely ICT and Health Sciences (biological effects of 

millimetre wave upon human cells, artificial biomembranes, cellular stress), as well as ICT 

and inorganic chemistry (reconfigurable ferroelectric microwave devices). 

Dr. Sauleau is the author or co-author of 1 book chapter, 53 journal papers, 8 invited 

talks in international and national conferences, and more than 100 contributions in 

international conferences and workshops. He also holds 3 patents. Dr. Sauleau received the 

2004 ISAP conference Young Researcher Scientist Fellowship (Japan) and was the recipient 

of the first Young Researcher Prize in Britany, France in 2001 for his research work on gainenhanced 

Fabry-Perot Antennas. He also was award the CNRS Bronze medal in 2008. Dr. 

Sauleau is a member of several Technical Program Committees and has chaired or co-chaired 

several poster and oral sessions in national and international conferences. Dr. Sauleau has 

been a Senior Member of the IEEE society since 2006.
